The 91618-420LF: It mounts surface-mount, accepts bottom or top entry, and includes a board lock for retention during reflow. The push-pull fastening mates without a latch.
The mated stacking height is 10.81 mm with a 0.275" (6.99 mm) insulation height.
The 91618-420LF belongs to the Amphenol Dubox series and is listed as Board-to-Board style — a dual-row female receptacle designed for surface-mount termination to mate with the matching male header on the daughter or stacked board.
The 91618-420LF specifies a mated stacking height of 10.81 mm and an insulation height of 0.275" (6.99 mm) — both dimensions govern the z-axis clearance and board-spacing budget in the target assembly.
